IMPROVEMENT IN SEWING-MACHINE FOR QUILTING.

The Schedule referred to in these Letters Patent and making paxt of the same.

To all whom fit 'may concern Be it known that I, TALLMADc-n 0. Foor, of Newburg, in the county of Pike, and State of Illinois, have invented certain new and useful Improvements in Quilt ing-Machines; and I do Ihereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forminga part of this specification, in which- Figure l is a top view of myv improved quilting-machine;

Figure 2, a longitudinal Vertical section, taken in the line :v-x, flg. l; l

vlligure 3, a transverse vertical section of the machine,'taken in the line 1j-y, iig. 2; and

Figure 1, a view of the double-hooked looper detached, showing the opposite face of the same from that shown in iig. 2.

Similar letters of reference denote like partsin all of the figures.

rlhe nature of my invention consists in the construction and arrangement of a traversing needle-boxing and bed-frame, for supporting the mechanism employed to impart motion to the needle-bar and hooks or loopers, in combination with stationary serrated bars and traversing-pinions,for propelling the machine over the fabric to be 'quilted or stitched, all hereinafter more fully described.

To enable others skilledin the art to make and use lmy 'improvedquilting-machine, I will proceed to de.

scribe its'construction and operation.

The lower stationary frame A, composed of two side and two end pieces, and a transverse bar, A', is provided on its inner sides, near the bottom thereof, with two longitudinal ways a a, running the entire length of the inside ofsaid frame, which serve to support and guide the reversible bed-frame'B, supporting the mechanism when propelled either backward or forward.

Y Frame Ais further provided with two stationary horizontahserratcd bars G, for giving the reversible frame B motion back and forth.

The centrally-located transverse bar A' extends suicieutly above the two side pieces of the main frame A to have secured to either'side of it the two longitudinal bars D, which are furnished, on their inner faces, with suitable ways b, for the boxing supporting the needle-bar to move on.

The reversible frame for supporting the mechanism employed to work the needle and looper, and to move itself over the fabric, consists of two longitudinal hars B, provided with suitable cross-bars, or braces B', the ends of which have grooves a n, for guiding said frame along the ways c, and acental head-block, lil, which is curved or extended upward, so as to form the two vertical supports F, for the bearings of the crank-shaft x and pinion d, which latter is secured to one end of shaft G.

' This bed-frame B is further provided with two .vertical standards H, in which the transverse shaft z has its bearings.

The upper longitudinal bar I, also forming a part of the movable frame, is secured, at one end, to the top of the head-block E, and to the upperV cross-brace Hf, connecting the two vertical standards H.

The other end of bar I serves to suspend the boxing J, supporting the needle-oar K, in which boxing the eccentric e has its bearings. Y

Secured toV crank-shaft a: is a cog-wheel, L, and bevelled pinion g. The cog-wheel L, meshing into pinion el, imparts motion to shaft G, which, in turn, gives the required motion to the eccentrics c and e thereon.

rlthe pinion g, being in gear with the bevelled-cog wheel M, imparts motion to the transverse shaft z, which, in turn, rotates the pinions t' fi, secured on each end of said shaft, causing them to traverse the serrated bars C, and thereby impart aV forward or backward motion to the machine, in accordance with the direc' tion in which the crank may be trued.

The needle-bar K receives its up-aud-down motion by means of the eccentric c and pitman e.

The eccentric c, on shaft G, is provided with a pitmau, j, which connects with a crank, k, secured to one end of shaft N,the other end of said shaft having a bevellcd pinion, m, gearing into the segments on the reversible looper P, secured to a transverse shaft, Q, having its'bearings in the two longitudinal bars B.

Thus, when the shaft G revolves, motion is imparted first to the eccentric c, which, in turn, moves the pitman j and crank lc, giv'ing the required motion to the rock-shaft N, thereby causing the looper, or hook-bar P to bring either one or` the other of its hooks p to catch the thread, in whichever way the mechanism may be moved.

The reel for the spool, and the required device for giving proper tension to the thread, I design locating as shown in the accompanying drawings, or at any convenient point on the upper part of the movable frame.

rIhe lower or main frameA of the machine should be stationary, either furnished with suitable supports, or secured to a table or stand, and the quilt, or other article to be stitched, may be placed in the relative position shown by red lines in iig. 2 of the draw- J:My improved quilting-machines, four feet two inches long, nine inches wide, and eleven inches high, make three hundred stitches in moving sixteen inches one way, and by simply adjusting thelooper or hook-bar,
